Injection Card

A highly innovative aerodynamic principle, ensuring gentle fiber treatment.

In the Injection Card, the traditional mechanical carding principle, using workers and strippers, has been replaced by an aerodynamic concept. In this highly innovative design, the fibers are injected against the following worker roller by the stream of air produced by the rotation of the main cylinder, and taken off the worker rollers by an aerodynamic effect generated by specifically shaped devices. This avoids considerable mechanical stress on the fibers, if compared to the traditional carding systems with stripper rollers: the carding action takes place at the tangent point of two convex surfaces and it is very smooth. Moreover, the fiber path is completely on the inside of the card, thus reducing the negative effects caused by centrifugal forces. Combined with the patented EVO-2 and EVO-3 take-off systems, the Injection Card achieves very high production speeds with an excellent uniformity, even when working with fine fibers.
